Description
This innovative product is a problem solution for humid rooms like
showers, bathrooms and sanitary rooms, in order to avoid fungus
growth on the walls and prevent damage to buildings.
In modern new type of buildings, the bathroom ( or even the “Kitchen”)
is also placed in the centre of the house and therefore is often without
a window. Therefore, to ensure a minimum air ow level, normally a
forced ventilation system is envisaged.
In previous ventilation concepts, the fan was either switched on
through a switch or by an automatic timer. The rst solution is not
comfortable and it performs wrongly by all means. The second
solution which is achieved by means of time control is functionally not
sufcient. Without regulation, such a ventilation cannot operate in a
power and demand optimised manner and results in problems like
fungus growth after some time.
All these disadvantages are ruled out by using our fan control for
humidity regulation. Then the fan runs only if it is necessary and
switched off again after some time with unwanted climatic conditions,
if after the change of air no more drying is observed
The device operates automatically, requires no maintenance or additional service and offers optimum protection from humidity and fungal
damage together with energy cost savings. The acquisition costs gets
amortised within a short time.

Humidity regulator for sanitary rooms
FREG-BAD
Functional description
The switching device is meant for triggering of a bathroom fan, in
order to ensure both the basic ventilation and also to maintain the humidity within a limiting value. As in the case for conventional devices,
there is an integrated timer and the fan is switched ON after the bathroom is occupied for at least 40 seconds (ON delay). Thereafter, the
fan runs with a time control for at least 5 minutes, in order to ensure
the basic ventilation after use of WC or the shower.
In addition, the control device also has an integrated humidity regulator which switches ON the ventilator, if a fast humidity increase is
registered (for example during use of shower) or if the humidity value
rises to over 70% rH. With this, the fungus growth in walls and room
corners is prevented, even if there is an unreasonable utilisation (e.g.
drying or washing) of water quantity involved. However, the fan is
operated only for a long time till the area is again sufciently dry, for
example, to save the heating costs in winter. Moreover, the device
also has a protective mechanism to prevent unnecessary running of
the fan, if for example, with unwanted external climatic conditions, no
further drying level can be achieved.
With a switch input, a timer controlled operation with ON delay and
OFF delay is also possible.
With a second switch input, the humidity regulation can be switched
OFF on demand. In this case, the ventilators are again put to operation by triggering through „Light“ based switch input.
Accessories (optional, not in scope of supply)
PIR-Sensor (Movement alarm unit) the optional sensor is for the
purpose of presence recognition. If a movement is detected for more
than 40 seconds in the area, then the timer controlled fan is switched
ON.
Safety instructions
The product should be installed and used only
according to the intended application.
The regulation device works on mains voltage.
Contact with live voltage parts leads to fatal
dangers. Therefore, tment and maintenance of the device shall be
carried out by only trained personnel. The device must be assembled inside a switchgear cabinet or in a fully closed plastic housing.
Mounting and servicing operations should be carried out only after
switching off the voltage.
Touching the electronic components in switched off condition should
also be avoided. Electronic components can get damaged due to
electrostatic discharge process.
The product is not meant for controlling electrical systems which
perform safety related functions. In normal operation also, there is always a danger of malfunctioning due to any fault or disturbance in the
output stage. The user has to ensure that there are no consequential
damages due to malfunctioning or undened switching status.
Due to wrong tightening of screws of the connection terminals or by
use of inappropriate tool, the terminals can get damaged because of
which the insulation or the contact can get disturbed. Badly connected leads can come out during operation and cause a serious risk
to safety. Due to contact resistance at terminal connections, there
can be increased heat generation which can cause re. Wrongly
wired connections can destroy electric components and cause other
damages.
While mounting the fans, legal guidelines and standards are to be
followed. Fire protection measures shall be duly taken care of !
Attention
Please avoid extreme mechanical and inappropriate exposure.
Light sensor: Alternatively, the presence detection can also be done
with an optional light sensor. This is possible, since bathrooms on the
inner areas do not have windows, and hence, while entering normally
the light is switched on.
By the application of PIR-Sensor or light-sensor, the wiring expenses
are reduced, since no switched phase of the light switch is to be
wired.
Dew formation sensor: In addition to humidity sensor, an optional
dew formation sensor can be used at cooling junctions to detect the
onsetting condensation. This results in an enhanced system safety
against fungus formation in critical zones (e.g. outside walls or room
corners).
